(The cities of Hiroshima and Nagasaki were bombed on 6 August, and 9 August 1945 respectively. The first, and thus far only uses of nuclear weapons in war) If the consciousness of universal brotherhood truly penetrates into the hearts of men, will they still need to arm themselves to the point of becoming blind and fanatic killers of their brethren who in themselves are innocent, and of perpetrating, as a contribution to Peace, butchery of untold magnitude, as at Hiroshima on 6 August 1945? Blessed Pope Paul VI, Message for World Day of Peace, 1967
